original application filed september 9, 19%, serial No. 587,07. named and this application filed August til, 1923. serial No. 658315.

TO allwhom it may camera:

Be it known that li, FRANK T, FRIDRICH, a citizen of the United States, residing at North Bond, in the county Dodge and State of Nebraska, have invented neW and useful improvements in Auxiliary Accelerators, of Which the following; is a Specification'.

This invention relates to control devices for motor vehicles, and more particularly to en attachment adapted to permit the driver of the Vehicle to control the speed of the motor by using either foot.

The present application is a division of my ending application filed September 9, 1922, Serial No. 587,087, covering an auxiliary accelerator.,

Tn the use of motor vehicles, particularly On long tri s, the foot Which operatesthe accelerator ecomes cramped, and it is customary for the driver to use the hand throttle, although, Were it not for the so called driverh cramp, the operator Would prefer to control the Speed of the motor by means of the foot. This is much more convenient, for the reason that it leaves both hands free to control the spark lever and steering mechanism, and, addtionally, because the foot accelerator automatically throttles down the motor When ressure thereupon is relieved.. llt is an OlOJGCt of the present invention to provide an additional r'oot operahle means for controlling gas supply, such means heing located upon the same side of the center of the car as the usual acoelerator, but laterally spaoed from such accelerator, 'WherehT the driver may use either foot for contro ling' the speed of the motor.,

A further object of the invention is to provide means of the character above mentioned Which may he readily attached to practicaliy any Vehicle.

The above and other objects of the invention may be aoeomplished hy devices Which. vary considerahly in their specific term, although, preferahly, the invention takes the form of a readily attachable mechanism Which'may he operated hy the left foot When, as is customary, the aocelerator pedal of the Vehicle is operable hy the right foot.

ln the accompanying drawings, there is shown one emhodiment of 'the invention, and in these drawings 2-- l 'ig, is a perspeotive view.

lFig. 2 is a side elevational view With the foot board of the Vehicle shown in action.

Referring to the dravvings, 10 indicates diagrammatically the foot board of the vehicle having the usual brake and clutch pedals indicated respcctively at 11, 12. Beneath the foot board is positioned a bracket 13 Carrying a lever 14 to Which is secured the accelerator pedal 15, extending up- Wardly through an Opening; 16 in the foot board. The pedal has an extension 17 Which is connected to a link 18 adapted to operate a bell Crank 19, through Which the accelerator pedal Controls the gas supply Valve of the carburotcr (not shown).

Ordinarily, the accelerator pedal 15 is positioned in ront of the driver' s seat, so that it may be conveniently Operated by the right foot of the driver. The additional means for controlling the gas supply should be placed in convenient position for the drivers left foot, and such a position, for instance, may be on the opposite side of the Clutch pedal 12, from the customary accelerator pedal 15.

lin the present instance, the additional accelerator pedal comprises an arm 19 Which is on any suitab le part of the accelerator mechanism; as shown, it is secured to the pedal extension 17, and has a pedal portion 20 extending upWardly through an opening 21 in the foot board. This arm is, preferably, an attachment for the Ordinary accelerator mechanism, to Which it may he readily secured. Tn the present instance, as Will he noted, it is attached by means of a two-part clamp 22, having holts 23 Which securely positlon the clamp upon the extension 17. One of the halves of the clarnp has an eye 24 Which receives the end 'of the arm 19, the latter being longitudinally adjustahle therein so that the pedal 20 may he adjust ed transversely of the Vehicle. set serevv 25 serves to retain the arm in ad justed position.

ilt Will be noted that the additional pedal may he adjusted in the clarnp eye 24 toward and from the pedal 15, so that the operator of the Vehicle may position the same relative to the clutch and brake mechanisms, and the 'ordinary accelerator, ,as is most convenient for him,

Tt -Wlll he ohserved that the-attachment may he readily applied to any type ci? ve- 'cations may be made in the structure illustrated and described as come Within the v seo e of the following elaims.
